Delayed Auditory Feedback vs Frequency Altered Feedback

The use of technology to enhance fluency can be divided into two methodologies
- Frequency Altered Feedback (FAF) and Delayed Auditory Feedback (DAF).

Delayed Auditory Feedback works on various platforms including certain
mobile apps (it started with Reel to Reel tape delay). It is the easiest
of the Altered Audio Feedback sounds to reproduce, however it has limitations.
There is defiantly a place for DAF on a mobile especially for low cost
evaluation purposes.

Frequency Altered Feedback is far more complex to reproduce. VoiceAmp
uses this method which includes noise suppression and other algorithms
to provide a superior solution. The technology used by the VoiceAmp
device cannot be replicated using mobile apps.

Some point to consider:

You can’t use the DAF effect while speaking on a mobile phone.

VoiceAmp devices support the Tele-coil option for the wireless receiver.

The VoiceAmp advanced noise cancelation (Noise gate) and close proximity
microphone help improve the effectiveness of this dedicated device.

The VoiceAmp adaptive algorithms prevent the so called ‘wearing off effect’
by adapting the audio profile continuously.

The VoiceAmp device is extremely robust and has long battery life.

The VoiceAmp device has undergone extensive clinical trials and meets
several international safety and quality standards.
